EDWARD J. SMITH, OF BEAVER FALLS, PENNSYLVANIA.

NAIL-MACHINE FEEDER.

SPECIFICATION forming part of Letters Patent No. 523,603, dated July 24,1894.

Application filed February 2, 1894- Serial No. 498,865. (No model.) A

To all whom it may concern.-

Be it known that I, EDWARD J. SMITH, a citizen of the United States, anda resident of Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented certain new and useful Improvements inNail-Machine Feeders; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification, and in-Which- Figure 1 is a perspective viewof my improved feeder. Fig. 2 is a longitudinal sec tional view of thesame on a horizontal plane through the middle, showing, in dotted lines,the play of the operating lever and itsdog. Fig. 3 is a transversesectional view on the vertical plane indicated by the broken line marked0000 in Fig. 2.

Like letters of reference denote corresponding parts in all the figures.

My invention relates to devices for'feeding a continuous wire blank tothe dies of a wirenail machine, of that type in which the end of thewire is grasped and held firmly in a dog (constituting part of thefeeder) while it is presented to the heading-die of the nailmachine; andmy improvement consists in the novel construction and combination ofparts of this dog or holder as will be hereinafter more fully describedand particularly pointed out in the claim.

Referring to the drawings, the reference letter Adenotes the base-plateor under side of a strong metal frame to which is fastened (or it may becast in one piece with the baseplate) a block B. On the other side ofthe flat base, opposite to blockB, is fastened (or it may also be castin one piece with the baseplate) an inclined or slanting block D. Theblock D, which is of the same height as block B, is covered with a plateF of triangular shape, but out 01f squarely at the apex or narrow end fof the frame, and presenting an inclined side F. Located between theplate F and the base A, is a horizontally movable dog or block H, formedwith apertures J, J, in which are journaled rollers L, L.. Upon itsupper side this dog is provided with a tween said rollers and block forthe insertion of the continuous wire blank P, as it is unwound from thecoil or reel (not shown). By now letting go the pin M, the spring N willforce the dog or holder H, back into its normal position so as to graspand clamp the wire P, firmly between the flat side of block B, and therollers L, L, in which position the projecting end w, of the 'wire ispresented to thedies of a nail machine, which as it forms no part of mypresent invention is not shown, but which may be of any desired orapproved construction. As the projecting end of the blank issuccessively cutoff to form the nails, the continuous wire is graduallyfed forward through the feeder by manipulating the pin M, so as toalternately release the wire as a new length is fed forward and clamp itfirmly as the projecting blank is presented to the nail machine to formthe nail from the blank.

Having thus described my invention, what I claim is- The combination ina nail blank feeder of the described type, of the frame comprising thebase plate A, straight side B, inclined side D, top plate F, havinginclined slot K,

the movable dog having an inclined and a straight side, the rollersjournaled in said dog, the pin secured to said dog and passing throughsaid slot, the post secured to the base, and the spring secured to saidpost with its free end bearing against said pin; substantially asdescribed. I

In testimony that I claim the foregoing as my own I have hereuntoaifixed my signature in presence of two witnesses.
